5.4.20 Increasing transmitter average power (S/L)
The pulse width is automatically changed as you change the range. However, if you want to

gives you sharp images with high distance resolution. The long pulse (LONG) provides higher
average transmit power and shows targets in large size for easy identification, although distance
resolution is reduced.
Press the "S/L" key to select the Pulse length (LONG or SHORT). The pulse length changes L
(Long) and S (Short) alternately.
Note: Refer to "5.5.3.8 Increasing transmitter average power(S/L)".
